Re: Data structure for new/old items codes

Hello,

Thank you for your answer.

Does hash table will be useful in this situation ?

a-> b-> c -> d -> e
f -> g -> h-> e
i -> e

I mean E is the current item code which replaces D,H,I.
A-I are old names in 3 chains.
I need to save for each letter (name) 12 numbers (demand for months).
In order to calculate E demand I need to sum A-I demands and add it to E demand (Edemand=Ademand+Bdemand+Cdemnd+...+Idemand)
